| 1 | Development and validation of a simple and multifaceted instrument,GERD-TEST,for the clinical evaluation of gastroesophageal reflux and dyspeptic symptoms显示文摘AIM To evaluate the psychometric properties of a newly developed questionnaire,known as the gastroesophageal reflux and dyspepsia therapeutic efficacy and satisfaction test(GERD-TEST),in patients with GERD.METHODS Japanese patients with predominant GERD symptoms recruited according to the Montreal definition were treated for 4 wk using a standard dose of proton pump inhibitor(PPI). The GERD-TEST and the Medical Outcome Study Short Form-8 Health Survey(SF-8) were administered at baseline and after 4 wk of treatment. The GERD-TEST contains three domains: the severity of GERD and functional dyspepsia(FD) symptoms(5 items),the level of dissatisfaction with daily life(DS)(4 items),and the therapeutic efficacy as assessed by the patients and medication compliance(4 items).RESULTS A total of 290 patients were eligible at baseline; 198 of these patients completed 4 wk of PPI therapy. The internal consistency reliability as evaluated using the Cronbach's α values for the GERD,FD and DS subscales ranged from 0.75 to 0.82. The scores for the GERD,FD and DS items/subscales were significantly correlated with the physical and mental component summary scores of the SF-8. After 4 wk of PPI treatment,the scores for the GERD items/subscales were greatly reduced,ranging in value from 1.51 to 1.87 and with a large effect size(P < 0.0001,Cohen's d; 1.29-1.63). Statistically significant differences in the changes in the scores for the GERD items/subscales were observed between treatment responders and non-responders(P < 0.0001).CONCLUSION The GERD-TEST has a good reliability,a good convergent and concurrent validity,and is responsive to the effects of treatment. The GERD-TEST is a simple,easy to understand,and multifaceted PRO instrument applicable to both clinical trials and the primary care of GERD patients. | Koji Nakada Nobuyuki Matsuhashi Katsuhiko Iwakiri Atsushi Oshio Takashi Joh Kazuhide Higuchi Ken Haruma | 2017 | World Journal of Gastroenterology2017，23，28： | 3 |
| 2 | Factors associated with complicated erosive esophagitis: A Japanese multicenter, prospective, cross-sectional study显示文摘AIM To assess the clinical characteristics of patients with complicated erosive esophagitis(EE) and their associated factors.METHODS This prospective, cross-sectional study included patients diagnosed with EE by upper gastrointestinal endoscopy between October 2014 and March 2015 at 106 Japanese hospitals. Data on medical history, general condition, gastrointestinal symptoms, lifestyle habits, comorbidities, and endoscopic findings were collected using a standard form to create a dedicated database. Logistic regression analysis was used to calculate adjusted odds ratios(aO R) and 95%CI for the association with complicated EE.RESULTS During the study period, 1749 patients diagnosed with EE, 38.3% of whom were prescribed proton pump inhibitors(PPIs) were included. Of them, 143(8.2%) had EE complications. Esophageal bleeding occurred in 84(4.8%) patients, esophageal strictures in 45(2.6%) patients, and 14(0.8%) patients experienced both. Multivariate analysis showed that increased age(a OR: 1.05; 95%CI: 1.03-1.08), concomitant use of psychotropic agents(a OR: 6.51; 95%CI: 3.01-13.61), and Los Angeles grades B(a OR: 2.69; 95%CI: 1.48-4.96), C(aO R: 15.38; 95%CI: 8.62-28.37), and D(aO R: 71.49; 95%CI: 37.47-142.01) were significantly associated with complications, whereas alcohol consumption 2-4 d/wk was negatively associated(a OR: 0.23; 95%CI: 0.06-0.61). Analyzing associated factors with each EE complication separately showed esophageal ulcer bleeding were associated with increased age(a OR: 1.05; 95%CI: 1.02-1.07) and Los Angeles grades B(aO R: 3.60; 95%CI: 1.52-8.50), C(a OR: 27.61; 95%CI: 12.34-61.80), and D(a OR: 119.09; 95%CI: 51.15-277.29), while esophageal strictures were associated with increased age(a OR: 1.07; 95%CI: 1.04-1.10), gastroesophageal reflux symptom(aO R: 2.51; 95%CI: 1.39-4.51), concomitantuse of psychotropic agents(a OR: 11.79; 95%CI: 5.06-27.48), Los Angeles grades C(aO R: 7.35; 95%CI: 3.32-16.25), and D(a OR: 20.34; 95%CI: 8.36-49.53) and long-segment Barrett's esophagus(a OR: 4.63; 95%CI: 1.64-13.05).CONCLUSION Aging and severe EE were common associated factors, although there were more associated factors in esophageal strictures than esophageal ulcer bleeding. Despite the availability and widespread use of PPIs, EE complications are likely to remain a problem in Japan owing to the aging population and high-stress society. | Masahiro Sakaguchi Noriaki Manabe Nobuo Ueki Jun Miwa Tomoki Inaba Norimasa Yoshida Kouichi Sakurai Masahiro Nakagawa Hajime Yamada Michiya Saito Koji Nakada Katsuhiko Iwakiri Takashi Joh Ken Haruma | 2017 | World Journal of Gastroenterology2017，23，2： | 3 |

| 4 | Kiso Multi-Fiber Spectroscope Project显示文摘A multi Fiber Spectroscope at Kiso Observatory is under consideration as our next instrument. In this paper we report an overview of our instrument and a scientific target of survey project. We are going to attach multi fiber system at the prime focus of Kiso 150m Schmidt telescope. This telescope has some advantage for our project. First, the effciency in survey for the objects, which number density is 0 1 to 10/degree 2, is higher than other multi object system due to the wide field of view (6 °×6 °). Second, an optics of telescope is well matched to fiber numerical aperture (NA) at an input end of fiber. Moreover, taking a focal ratio degradation (FRD) and scrambling property into account, since the light from object does not move at the entrance slit of spectroscope, we could get spectroscopic data stably with this system. We select a fiber with 100μm core which corresponding to 6 arcsec on focal plane, that is matched with a typical seeing (3 arcsec) at Kiso Observatory and set 150 fibers to one field. For efficient observations, it is necessary to arrange fibers accurately within an accuracy of ±25μm on the curved focal plane during a typical exposure time (1 hour). Therefore we examine a particular positioner specialized for curved surface. We also develop a spectroscope that is suited for a fast focal ratio and proceed with making its design. One of our main key projects with this system is a non biased survey for solar neighbour stars. We are now establishing a new metallicity determination method that easily and reliably measures a metallicity from low dispersion spectra. (see Itoh it et al. 1998) As we consider our main target as Galactic objects and low resolution (R is around 1000), we could observe a star with 17 mag at V band (1 hour exposure). | Yasushi Yadoumaru, Nobunari Itoh, Yoshikazu Nakada, Ken’ichi Tarusawa, Takao Soyano Kiso Observatory, Institute of Astronomy, The University of Tokyo and Hiroyuki Mito The Graduate University for Advanced Studies | 1999 | 天文研究与技术1999，，S1： | 0 |
